You can't pull the quarz frequency enough to get +-75kHz frequency deviation for wideband FM (87-108MHz). Its only good for Narrow FM applications (NFM=+-2.5kHz). 27MHz on CB-Band should work, you will hear the sound loud enough.
Bi zamdn fm icin cok ugrssmistim ve vericiyo de uzaktan ac kapa yapmak istemiştim vericiye farkli bir frekasta konrol etmek cok istiyorum bu cok mu zor
hii.. i made this with 100MHz xtal. it can received by fm radio, but the audio is very low, even in full volume (input source & radio receiver). i try to use mini amplifier as input in this circuit, but the audio quality is terrible. how to fix this? to improve the audio quality

@@blechhammerer4008 i tried another schematic, and worked. Audio quality is better. I use 2 pieces 100MHz xtal in parallel to improve audio qualily. Now i have stable FM transmitter.
@@blechhammerer4008 i use this schematic th-cam.com/video/FauFCfy4jeM/w-d-xo.html I use this scheme, with the adjustment of 2 pieces 100 MHz crystals installed in parallel. and by adding 2 stages of RF amplifier to extend the range.
I know this comment is kinda old but i'm having trouble understandig the vales of the components, you say that r1 should be 47 kOhms, so what is the value for r2 and c3?
@@francogaretto2479 Hello! I am from Russia and you asked me a question (I wonder what country you are from? If you want, tell me here). There are two versions of this transmitter. Artyom (the author of this video) showed it to us. The second version is the Chinese Module= fs1000a. I think the Chinese module is better. Resistor R1 is assigned with a power source supply: at = 3 V, as = 22÷27 Kohm, at = 6 V, as = 33÷39 Kohm, at 9÷12 V, as = 47÷ 56 Kohm. We make other components without changes.
Not true at all. An end fed full wave antenna is a very high impedance. If you want a better antenna use a half wave at the feed point and another have wave from ground.
A quarter wave length ground plane antenna would be good for this project. There are antenna wavelength calculators on the web (m0ukd antenna calculator). For the frequency he was receiving which was 433.940 MHz the vertical monopole radiating element is calculated at 16.4 cm and the 4 radials would be cut to 18.4 cm bent at 45 degrees connected to the ground of the UHF connector. A short length of coax could be used or the ground plane antenna could be directly connected to this circuit and the whole thing located high up in the room near a window hung from the ceiling of the room with some non-conductive string or cordage.
TLDR: yes, replace the crystal with a 100MHz (or so) one explanation: his radio is a dual band FM transceiver so if it can receive his FM radio broadcast at 433MHz with such an oscillator, if you replace the crystal oscillator you'll be able to broadcast on a different frequency but with the FM modulation because of the circuit
@@evieanindyaputri610 you don't have to adjust anything, however you will have to adjust the r2 or c2 if the circuit won't oscillate. if you find yourself having a small range, try adjusting c1 and l1. also a good idea is to use a low pass filter on the antenna output so you don't send out harmonic waves outside of the FM band.
You are back! Nice to see you again on youtube. Английские субтиры и фоновая музыка украсят видео, и помогут зайти англоговорящей аудитории. ;)
Why a 11,5cm Antenna and not 17,3cm?
Very nice 👍
Hope to see it with a microphone input
thank you for all your clip!!! very very excellent... good lock
ZQ1 is a SAW-Filter with 433.92MHz?
Which type? About Z~50 Ohms when in resonance?
congrats!
How do I do it with a simple on/off switch? What do I add instead of a microphone?
😂❤alles schöner Milliwatt Spaß mit Quarzoszillator.Hauptsache Oberwellen Dämpfung!
what's the value of L1 inductor? 10uH or 10nH?
Nice video as usual
Professor, are there long-range UHF transmission circuits?
I am missing the Feedback capacitor between Collector and Emitter BFR93.
Does it work without that C?
Please explain the working of this circuit
Please make a video on Circuit diagram of 433 mhz receiver
Man....man..... You are e.t.... congratulations..... Nice ...nice....
Wait to see another video with amplif stage
Could you publish how the tester you use is made?
Great Artem, what is the main difference between this transmiter on 433 and the FS 1000 a arduino modules on 433 mhz respecting power OUTPUT? CHEERS
Where did you get this circuit schematics from?
Muito top nessa freqüência ai gostei 🙋👏👏👊

Harika devre olmuş
Peki orada gerilimi degistirincemi mesafe artar akimi artinca mi
Her iki durumda da frekans değişir mi

would it also work with an 100 mhz or 27 mhz crystal?

Is it uhf band(ham) transmission?
HAM and ISM
I love it good 👍

Dear Artyom! You are not right. The resistor should have a value of 47 kOhm, and your circuit contains a resistor with a value of 4.7 kOhm.

Make the antenna 70cm in length and you will have a full wave output. It will go even further :)

Can you buit one stage rf amplifier?
Can you make one that works in 2.4ghz or 5.8 GHz or upper?
Recommendation: Aliexpress is selling such ready modules. For this high frequency its hard to make own schematics/layouts.
@@blechhammerer4008 thanks for attention, do you have some link to recommend for me?
Can this be adapted to 868mhz ?
500m?
Can I replace this crystal with L/C tuned on 433?
will not be stable enough
Si coloco un cristal de 1Mhz, funciona?...
